摘要
The disclosure teaches a method of simulating natural desert varnish (that requires at least decades to produce by nature) within a few days. The method is broadly exemplified by the steps of applying a strong base followed by application of a soluble iron or manganese salt. Optionally, sodium hypochlorite may be applied as an additional step after the metallic salt application to speed up the process. The resulting product is difficult to distinguish from the natural varnish.
